Description

Device for marine salvage on ship

Technical Field

The invention belongs to the technical field of marine rescue tools, relates to a fishing device, and particularly relates to a marine fishing device on a ship.

Background

The ocean occupies a large area of the earth, people inevitably can move on the ocean and encounter various dangers during the operation on the ocean, and the people need to rescue quickly when falling into the ocean carelessly. When a ship is used for rescue, people falling into the water are pulled up by using ropes, hanging ladders and the like, but the falling state is very different, the height of a ship body is high, the people falling into the water are easily damaged by sea surface storms or worrying about that the ship body is close to the ship body, and rescue by using the tool is not convenient in some cases. In addition, aiming at special marine environments, for example, oil stains on the sea or fire is inconvenient to stay on the sea for a long time, and some injured or unconscious people are also inconvenient to pull by ropes or hanging ladders, so that secondary damage is easily caused, and difficulty is brought to rescue.

Chinese patent (publication number: CN 102632976B; publication date: 2014-11-26) discloses a marine anchor system fishing device, which comprises a fishing rope and an annular lifting lug, wherein one end of the fishing rope is provided with a sinking anchor, and the other end of the fishing rope is connected to a fishing ship; the fishing device also comprises a plurality of fishing hooks which are tied on the fishing rope and are positioned between the sinking anchor and the fishing vessel; the fishing hook comprises a main rod and array barbs arranged on the outer wall of the main rod; the number of the arrayed barbs is 5-15, and each layer has 4-8 barbs; the annular lifting lugs are arranged at two ends of the main rod.

The patent document uses the fishing hook with the array barbs, hooks objects through the barbs for fishing, can only be used for fishing garbage or foreign matters, and is not suitable for marine rescue; is easy to cause damage to human body.

Disclosure of Invention

The invention provides a device for marine salvage on a ship aiming at the problems in the prior art, and the technical problems to be solved by the invention are as follows: how to provide a safe and efficient device for fishing people falling into water.

The purpose of the invention can be realized by the following technical scheme:
